My copy arrived today and I put it in for an hour or so. Looks pretty good.
Question: are there any non-plot-related, niggling missable things that are better off known about before starting the game? I just found a "Sticky Note #2" on my Abstergo desk but never saw #1. I also saw many treasure chests appear on the map of the prologue area just as I got on a boat, possibly to sail away from there forever. Will there be chances to wander aronud and revisit old areas and pick up missed stuff?
Also, regarding AC3 and ACR: count me in with the Revelations fans. My men indeed. That game had the best multiplayer, some seriously-underappreciated short multiplayer music tracks, and we got to learn what finally became of both Altair and Ezio. The main story was short, but Constantinople was a great place to visit, and I really enjoyed it.
As for AC3, all my problems with the game were on the game-design side. Connor was fine. I didn't mind his voice actor; I loved hearing people speak Mohawk -- I intentionally hung around the starting point and failed the hide-and-seek mission during Connor's childhood, just so I could hear the other voice actor count up to 30 in Mohawk!
Where the game dropped the ball again and again was with the gameplay.
I remember railing epically about the crescendo of fail that was reached when, after driving me insane with insipid exhortations to go hunt some stupid bobcat in the middle of an extreemly difficult timed, straight-path mission towards the end, it then shoved even more sidequest cruft right into the very last mission of the game and ruining it utterly.
I like sidequests and off-the main-track stuff -- remember those great Truth puzzles in AC2? -- but AC3 was over-the-top ridiculous with them.
Other stuff was criminally under-used. I thought for sure that those tunnels were going to be something bigger than they were, and that when you visited New York as Desmond you would maybe explore them again by entering an unused maintenance door in a subway station or something cool like that, echoing your re-visit to today's Monteriggioni in ACB, but no, they swung and missed on that. When I first hid in a crowd as Desmond in the Brazil chapter with no HUD or other audio clue to tell me I was "hidden", I thought we'd get a chance to test our assassin skills as Desmond, fully integrating them without the Animus as a crutch, but no, the final Desmond chapter was just disgusting straight-up butchery.
Now I'm ranting about AC3 again. Let's hope that this game is an improvement.
